Abstract
A method to determine a position of a lens that concentrates an optical beam on an inclined end surface of an optical fiber is disclosed. The method first determines two positions at which optical power output from the lens and measured through a multi-mode fiber becomes a maximum on respective virtual plane apart from the lens; then, calculates the direction or the angle of the optical beam output from the lens, and moves the lens so as to compensate a deviation of the calculated direction from the designed direction.
